[PSUBS-MAILIST] Gamma hatch

[hank pronk via Personal_Submersibles]

Brian,
I will look forward to a picture of your CT and hatch.  In particular I would like to see how you transition from the elliptical portion to the 1 1/2in wide ring.

 Hi Hank,
            I bought two
 stainless rings 1/2" thick by 1 1/2" wide (18" id). Which
 will be welded on to the conning tower and the hatch, then a
 o ring groove put in the hatch side.  With the drop I
 was able to get 6  - 6" disks which I'm going to make
 into electrical inserts that will go into two of my
 viewports.  
   Conning tower getting welded today ( 8 viewports) and
 also working on the other viewports on the sphere, got two
 welder friends that I have working on them, both 30+ years
 of commercial welding experience !

 Brian,
 What did you do for the hatch seat on the conning
 tower.  Is it stainless or did you do like Gamma has, a
 layer of stainless welded on.

  Hank,           
  Do you know how big the shaft is that goes through the top
  of your hatch?  Have you every had to disassemble it
  ?  My hatch is pretty much identical to Gamma's,
  I'm in the process of cutting in a little viewport in
  and also that rotating hatch closure shaft / thru  hull
  deal.   Seems like at least a 3/4" shaft
  would be in
  order. Brian
